Short intermediate and long acting corticosteroids

When the necessary conditions of the reaction no longer prevail, these intermediates react further and no longer remain in the reaction mixture. There are some operations where multiple reactions are run in the same batch. For example, in an esterification of a diol , a monoester product is formed first, and may be isolated, but the same reactants and conditions promote a second reaction of the monoester to a diester . The lifetime of such an "intermediate" is considerably longer than the lifetime of the intermediates of the esterification reaction itself (the tetrahedral intermediate ).
